Abstract
A magnetic head for a magneto-optical recording device for magnetically recording information onto a magnetic recording medium under the condition where the magnetic recording medium is heated by irradiation of a laser beam. A leakage magnetic field is effectively suppressed by a skin effect, and a magnetic field due to an eddy current is effectively summed up with a magnetic field generated from the core end, thereby increasing an intensity of a total magnetic field to be applied to the magnetic recording medium. Further, a distribution of the magnetic field intensity at the core end can be easily adjusted to stably and widely apply the magnetic field to the magnetic recording medium.
